BUILDING AN AEM API CLIENTS ECOSYSTEM

Cliffano Subagio - Michael Diender - Stephen Shim Shine Solutions

Agenda

• A little bit of history • API clients ecosystem • Demo applications • To do list

AEM 5.6.1

Q: How do you deploy a package?A: Use this curl command.

Q: Really?

Q: How do you …?A: Use that curl command.

Problems

• curl —fail is not fail-safe • Can’t rely on exit code • Can’t rely on HTTP status code • Need to parse response body • Unexpected AEM state

API client

• A helper library • Authentication • HTTP request/response • Debugging

Why API client?

• First class for your tech stack • Better error handling • Simpler response body parsing • Easier integration with 3rd party tools

Moarrr clients

• In 2014: wrote an AEM Python client • In 2015: wrote an AEM Ruby client • Other clients written by others

There’s got to bea better way

Swagger

• An API framework • Open API specification • Swagger Codegen

API client ecosystem

• More than a single client • Centred on Open API specification • Generate all API clients

TODO

• Python, JavaScript, and Java clients

(in progress) • More languages support?

TODO

• AEM 6.1 Assets API • 100% generated clients
